Vitamin b-12 is important for the synthesis of which serves to insulate nerve cells.

Vitamin B-12 is important for myelin synthesis. Myelin serves to insulate the nerve cells.

Further Explanation:

Vitamins are the important micro-nutrients that are needed for proper functioning and metabolism of an organism. The vitamins are water-soluble or fat-soluble. Vitamins A, D, E, and K are fat-soluble vitamins while vitamin B and C are water-soluble.

Vitamin B-12 or cobalamin is the water-soluble vitamin that acts as a cofactor in the synthesis of DNA (deoxyribonucleic acid). It has a complex structure. The vitamin B-12 sources include meat and other animal products, like dairy. The absence of these products in the diet of vegan makes them highly vulnerable towards the condition called pernicious anaemia. It is, therefore, suggested to vegans to have supplements of vitamin B-12 for fulfilling the daily vitamin B-12 needs of the body.

Vitamin B-12 is involved in amino acid and fatty acid synthesis too. The other important functions of vitamin B-12 are observed in the maturation of developing RBCs (red blood cells) in the bone marrow and myelin synthesis. Thus, this vitamin has a major role in neurological health. It helps in development as well as functioning of the nerve cells as it plays a key role in maintenance of myelin sheaths, which protect and covers the nerve cells of the nervous systems (central and peripheral nervous systems). The myelin sheath ensures fast nerve impulse transmission from one nerve to another. Therefore, lack of myelination results in dysfunctioning of the central as well as peripheral nervous system.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
